Frown. Sorry, I'm not sure what "p615", "power4" and "no-hmc" is. I

However, you seem to be suggesting that a terminal application somehow
forwards the ctrl-sysrq (and it's actually alt-sysrq). Maybe it does,
maybe it doesn't. Probably depends on the terminal application itself.
Eg, with minicom, you need to ask minicom to create the serial break
event itself, normally by (assuming default configuration) <ctrl-a> <f>.
I don't think you've addressed my concern... but I'm afraid I haven'tThe point i was trying to make was to have a consistent behavior across

In any case, applying this patch means that you _permanently_ prevent

console or not.
With this patch, I guess it's tough luck if you have a modem connected
to your PC and you want to run ppp or x,y,z modem protocols.
